Oh, but the situation is different. For BY-SA at least.
Person 1 can take his own copyrighted work and distribute it under
BY-SA and ARR.
Person 1 can take his own copyrighted work and distribute it
"protected" by DRM and in the clear.
Person 2 can take person 1's BY-SA licensed copyrighted work and
distribute it under BY-SA.
Person 2 cannot take person 1's BY-SA licensed copyrighted work and
distribute it ARR.
Person 2 can make a derivative of person 1's BY-SA licensed copyrighted
work and distribute it under BY-SA.
Person 2 cannot make a derivative of person 1's BY-SA licensed
copyrighted work and distribute it ARR.
Person 2 needs to seek person 1's permission to do the "cannots" above.
You want person 2 to be able to take person 1's BY-SA work and
distribute it or a derivative of it "protected" by DRM and in the clear
elsewhere without seeking person 1's permission. This is different than
the dual license situation.
all the best,
